cpu load

Hi,
the load on linux systems is considered high when it is higher than number
for CPUs seen by the system. The value is a number of processes waiting in
queue to get CPU time (even if it is waiting for disk I/O), not a
utilisation in percentage so 50/55 is too high unless you have a server
with 40-48 CPUs/cores. My default setting is "LOAD 5.0 10.0"  for all
machines with 4 CPUs.

Regards,
Martin

Not if it's not a good idea for you to have a load of 55 on your system.

I just got a critical on a system saying that my load was critical:

But it is not under load:

So in my localcient.cfg, I changed the load on cpu to 'LOAD    50.0 55.0'

Was that a good idea?
